Abstract

. Stellaroccultationsandtransitsoccurwhenaplanetarybodypassesinfrontofastar(includingour Sun). For objects with an atmosphere, refraction plays an essential role to explain the drops of flux and the aureoles observed during these events. This can be used to derived key parameters of the atmospheres, such as their density, pressure and temperature profiles, as well as the presence of atmospheric gravity waves and zonal winds. Here we derive from basic principles the equations that rule the ray propagation in planetary atmospheres, and we show how they can be used to derive the physical parameters of these atmospheres. Les occultations stellaires et les transits se produisent lorsqu’un corps planétaire passe devant une étoile (y comprisnotreSoleil).Pourlesobjetsavecuneatmosphère,lerôledelaréfractionestessentielpourexpliquer les chutes de flux et les auréoles observées lors de ces événements. Ces derniers peuvent être utilisés pour déduire des paramètres clés des atmosphères, comme leurs profils de densité, de pression et de température, ainsi que la présence d’ondes de gravité ou de vents zonaux. A partir des principes fondamentaux, nous déduisons les équations qui régissent la propagation des rayons dans les atmosphères planétaires, et nous montrons comment elles peuvent être utilisées pour déduire les paramètres physiques de ces atmosphères.

通过掩星或行星凌日对太阳系大气的研究
.stellaroccultationsandtransitsoccurwhenaplanetarybodypassinfrontofastar(包括我们的太阳)。对于具有大气的物体,折射在解释这些事件期间观察到的流体和光晕的下降方面起着至关重要的作用。这可用于推导大气的关键参数,如密度、压力和温度系数,以及大气重力波和带状风的存在。在这里,我们从基本原理中推导出控制行星大气中光线传播的方程,并展示如何使用它们推导这些大气的物理参数。恒星掩星和凌日发生在行星体从恒星(包括太阳)前面经过时。对于大气的目的,折射作用对于解释这些事件中观察到的流体下降和光环非常重要。这些可用于推断大气的关键参数,如密度、压力和温度,以及重力波或带状风的存在。从基本原理中,我们推导出控制行星大气中光线传播的方程,并展示了如何使用这些方程推导这些大气的物理参数。

期刊介绍: The Comptes Rendus - Physique are an open acess and peer-reviewed electronic scientific journal publishing original research article. It is one of seven journals published by the Académie des sciences. Its objective is to enable researchers to quickly share their work with the international scientific community. The Comptes Rendus - Physique also publish journal articles, thematic issues and articles on the history of the Académie des sciences and its current scientific activity. From 2020 onwards, the journal''s policy is based on a diamond open access model: no fees are charged to authors to publish or to readers to access articles. Thus, articles are accessible immediately, free of charge and permanently after publication. The Comptes Rendus - Physique (8 issues per year) cover all fields of physics and astrophysics and propose dossiers. Thanks to this formula, readers of physics and astrophysics will find, in each issue, the presentation of a subject in particularly rapid development. The authors are chosen from among the most active researchers in the field and each file is coordinated by a guest editor, ensuring that the most recent and significant results are taken into account. In order to preserve the historical purpose of the Comptes Rendus, these issues also leave room for the usual notes and clarifications. The articles are written mainly in English.
